It has been reported that biventricular pacing can improve the symptomatic status of patients with heart failure. However, using currently available transvenous left ventricular pacemaker leads the implantation procedure is difficult and has a high failure rate. We report the successful use of a new type of left ventricular pacing lead, the 'side-wire' pacing lead. This lead is initially introduced through a specifically designed guiding sheath to aid coronary sinus cannulation and then over a pre-positioned guide wire to aid final positioning. The more widespread introduction of this type of left ventricular pacing lead may reduce the difficulty of left ventricular pacing via the coronary sinus and thus improve the overall success rate of this therapeutic approach.
据报道，双心室起搏可改善心力衰竭患者的症状状态。然而，使用目前可用的经静脉左心室起搏导线，植入过程困难且失败率高。我们报告了一种新型左心室起搏导线——“侧线”起搏导线的成功应用。该导线最初通过专门设计的引导鞘管引入，以辅助冠状窦插管，然后越过预先放置的导丝以辅助最终定位。这种类型的左心室起搏导线的更广泛应用可能会降低经冠状窦进行左心室起搏的难度，从而提高这种治疗方法的总体成功率。
